I haven't done a swap, but from what I've seen an M50 swap with the right parts is very straight forward. A turbo setup is the opposite, LOTS of hassles, lots of nitty little details, with solutions that tend to be unique to each setup. M50 swap looks less of a hassle.

QFT...I have done both, an 24v swap is a cakewalk in comparison to a turbo build.
